采用oshi，主要 API

oshi.SystemInfo;
oshi.hardware.CentralProcessor;
oshi.hardware.GlobalMemory;
oshi.software.os.FileSystem;
oshi.software.os.OSFileStore;




SystemInfo systemInfo = new SystemInfo();
# 获取CPU个数
CentralProcessor processor = systemInfo.getHardware().getProcessor();
int cpuNum = processor.getLogicalProcessorCount();

# 获取内存信息
GlobalMemory globalMemory = systemInfo.getHardware().getMemory();
long total = globalMemory.getTotal();
long available = globalMemory.getAvailable();

# 获取文件信息
FileSystem fileSystem = systemInfo.getOperatingSystem().getFileSystem();
List<OSFileStore> osFileStores = fileSystem.getFileStores();

List<FileStoreModel> fileStores = osFileStores.stream().map(osFileStore -> {
      String mount = osFileStore.getMount(); // 盘符
      String type = osFileStore.getType(); // 盘符类型
      String name = osFileStore.getName(); // 文件类型
      long totalSpace = osFileStore.getTotalSpace(); // 磁盘总大小
      long usableSpace = osFileStore.getUsableSpace(); // 磁盘剩余大小
      return xxx;
}).collect(Collectors.toList());
